“In a world gone niche, NCIS keeps getting bigger, and Mark Harmon continues to define the role of leading man on the No. 1 show on television,” said CBS President and CEO Les Moonves in a statement. “NCIS is the type of franchise every company wants in today’s global content ecosystem — high-quality storytelling that generates passionate viewers and drives revenue on every conceivable platform.”

CBS is said to be still in negotiations with Harmon’s co-star, Cote de Pablo, whose deal is also set to expire at season’s end. (The rest of the cast is locked in.)

Currently in its 10th season, NCIS ranks as TV’s most-watched drama series with an average audience of 21.48 million viewers.
